Solutions

1. Do not call updateObject on a SQL federation result set; it is read-only.
2. Materialize the rows, update them locally, and write changes back with a separate DML statement.

When it happens

Trigger: An application invokes an updater method on a read-only SQL federation result set.

Common situations: ORM or legacy code using updatable ResultSet semantics against SQL federation queries.
